Measure swingweight | Tennis racket customization

In this video, we take a look at how to measure swingweight. It's one of the essential parameters you have to work with when customizing rackets. For more information on swingweight check out my web page.

  1. Can you explain how far you should swing it? Doesn't the distance you swing the racket impact the calculation? Like if it was swinging from a very large angle versus a smaller one? Doesn't this change the timing? I know you said <10 degree, but like isn't there a big difference between the measurements you would get at 10 degrees and 6 degree for example?

  2. hi, wouldn't this method give more weight — pun intended — to mass at the bottom of handle rather than to weight at the top of the hoop? In other words, wouldn't it be more accurate to swing the racquet with the racquet face pointed down rather than pointed upward?

  3. Hi Miha! Thanks for sharing your videos and website.
    When I use your method I don't know if I should consider the moment when the racket changes direction or a fixed point to measure the time.

    In the first case I get different results if I wait 10 or 20 swings for example.

    With the fixed point, the result doesn't change according to the number of swings, but it doesn't match with customization tools from your website.

    Thanks for your help.

  4. I'm not sure if anyone talked about this but depending on the FPS you film at, you have to convert the FPS shown in the shotcut video to miliseconds. For example, lets say you are recording at 60 FPS and the starting frame was at 2.26 and 10th swing stops at 16.16. You have to divide 26/60fps = 0.433ms so the starting time will be 2.433s and divide 16/60fps = 0.267ms so the 10th swing stoping time wil be 16.267s. total time will be 16.267s -2,433s = 13.834s. I got pretty consistent results using this method. And maybe there is a easier way to display the correct time in the shotcup app?
